Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureIndian merchants must issue a tax invoice for every sale, with the CGST+SGST versus IGST split decided by where goods ship from and ship to. This app does that as orders arrive, working the tax out itself rather than copying Shopify's tax lines. A GST invoice cannot legally be changed once issued, so refunds raise credit notes and order edits raise debit notes.
GSTSolve creates a compliant GST tax invoice the moment an order is paid. Enter your ABN or NZ GST number once; every invoice then follows Australian (ATO tax invoice) or New Zealand (IRD taxable supply information) requirements. Invoices use sequential numbering with no gaps, carry your prefix, attach as PDFs to an automatic customer email, and can be re-downloaded from a secure link.
